In a CDMA system, forward link load measurements and mobile station channel measurements are provided to the base station controller to allow the controller to jointly select the initial traffic channel transmit power and data rate. A mobile station reports a received pilot channel signal-to-noise ratio for all base stations in sight to a base station controller. The base stations report a current forward link load estimate to the base station controller. The base station controller sets a number of traffic channel connections and a traffic channel data rate to be allocated for the traffic channel connections, and sets a target traffic channel signal-to-noise ratio based on the data rate and the number of traffic channel connections. The initial traffic channel power is computed by the controller based on estimated forward link channel characteristics, the target traffic channel received signal-to-noise ratio, the base stations' load, the number of traffic channel connections, and the traffic channel data rate.
